ompatibility
According to the EC directive (89/336 EEC) regarding electromagnetic
compatibility (short EMC Directive) there are requirements regarding the
capacity of electrical and electronic equipment, installations, systems or
components to operate satisfactorily in the given electromagnetic environment.
The devices must not interfere with their environment and must not be
adversely influenced by external electromagnetic interference.
Ethernet
Ethernet is a widely used, manufacturer-independent technology which
enables data transfer in the network at a speed of 10 or 100 million bits per
second (Mbps). Ethernet belongs to the family of so-called "optimum data
transfer" on a non exclusive transmission medium. The concept was
developed in 1972 and specified as IEEE 802.3 in 1985.
FE FE

arth
Functional earth is a reference potential which is not connected to protective
earth or only connected when special measures are taken. The functional
earth serves as equalisation of potential for an ungrounded installation (e.g.
→
SELV).
Fieldbus
A
→
bus for industrial applications: mechanically extremely robust and
excellent data protection
Firmware
Basic program in the device, virtually the operating system
The firmware establishes the connection between the hardware of the device
and the user software.
Gateway Coupler
Gateways enable connection of completely different systems. Gateways are
used when two incompatible network types are to be connected by converting
the protocol of one system to the protocol of the other system.
Here: connection between AS-i and higher-level fieldbus systems such as
→
Profibus DP,
→
DeviceNet, Interbus-S or other interfaces, e.g. RS-485. The
device includes an AS-i master which is directly coupled to the
→
host interface
(e.g.
→
Profibus DP slave).

Describes the interface to the device to be connected to the fieldbus. The file
is provided on the

folder "Gateway").
Host
The controller in the hierarchy above the AS-i master, e.g. a PLC or a
processor.
ID ID

Id
entifier
Name to differentiate the devices / participants connected to a system.
IP address
IP =

nternet
P
rotocol
The IP address is a number which is necessary to clearly identify an internet
participant. For the sake of clarity the number is written in 4 decimal values,
e.g. 127.215.205.156.
Jitter
Jitter means a slight fluctuation in accuracy in the transmission cycle when
transmitting digital signals. More generally, jitter in transmission technology
means an abrupt and undesired change of the signal characteristics.

In this slave list the controllere enters the slaves detected as active for this AS-
i master.
